Silvery-blue light streaking across sky, South to North, 1:00 o'clock high to 2 o'clock. Turned to yellow-orange color at 2:00 o'clock high before going out of sight.

My husband, aged 59, and myself, aged 57, were traveling West in our car on Kilpatrick Street.  The light in the sky that we observed was oval in shape and silvery-blue in color.  The object was very high in the sky and appeared to be about the size of a dime held at arm's length.  It traveled much faster than an airplane or jet and traveled across the sky from South to North and out of sight in a matter of about 7 seconds.  Just before it disappeared, it changed to a yellow-orange color.
